(granted undenthe act of March 1883, ,as amended April 30,1928; 370 (Bi- 7 57) Claims.

The invention described herein, if patented may be manufactured and .usedbytor for the Government for governmental purposes without the paymentbfany royalty thereon. 1

This invention relatesto animproved separable valve and more particularly to a form especially adapted for-use in connection with a fuel line and control valve coupling structure covered by separate application and provides a valvethat may bequickly separated for cleaning or replacement of parts and was designed for use more particularly in the recently constructed Army portable range.

The object in view is to provideasimple; durable and inexpensive valve th-at may be produced pointed out in the appended'claims.

While the preferredlembodiment of this invention is shown and described,zit willbe understood that slight changes in form and minor details of .constructionmay be resorted to without departing from thespiritl of the invention or fall beyond the scope of the claims.

Similar numerals indicate corresponding parts in all the figures of the drawing in which:

Fig. 1 is a fragmentary viewof a portion of a burner with the improved valve in position.

Fig. 2 is an enlarged vertical longitudinal section of the valve.

Fig. 3 is a plan view of the valve.

Fig. 4 is a side elevation of a portionof the valve.-

Fig. 5 is asection on line 55 of Fig. 2.

Reference now being had to the drawing by numerals, I indicates the valve mounted in a sleeve 2 of asupporting plate 3, said valve as shown discharging into the mixing chamber 4 of a burner indicated at 5, said burner being provided with a fuel tube 6 and an extension 1 adapted to be in communication with the valve through a lateral opening therein. The supporting plate is provided with a slot 8 to be described later.

The valve consistsof the body '9, the stem H), the gland II, the jet l2 and the nut I3.

The body 9 of the valve is providedwith a lateral fuelinlet opening 14, to which -,-a.liquid or vapor fuel tube 1 maybe connected in any preferred manner, the form shown beinga contact joint formed by ground maleand female surfaces on and in the end of the fuel tube and-said opening in the valve'body respectively. Said manner of joining the fuel tube and thevalve being shown astheone most desirable with the present Army portable range, to enable quick; disassembling and assembling of the parts'as is required by the Army, dueto practically continuous use of the a projecting pin I5 that, when.-the valve is burner of which the form of valve here shown is a part. The valve body =9 of the valve is provided with mounted one. supporting plate 3, is adaptedto pass through the slot 8 in the plate and when the ,valve body isgivenaslight rotary movement the pin l5 willbe caused topass inrcar of theplate at one side of slot 8 and lock the valve in;place. The body 9 of the valve is provided with a bore having a relatively reduced portion Hi, the screw threaded portion l1, acylindricaliportion I8, an

inner packing shoulder I Band an enlarged partly threaded portionlfl. The discharge end of the body portion is concave as shown at 2|.

The jet I2 is providedwith a convex surface 22 adapted to-be seated in the concave end 21 0f the body 9 and forms a continuation of said body. The jet is further provided :With a needle valve seat23 and a shoulder 24. k i The nut I3 is threaded at2 5 on the end of-the bodyll of the valve and is provided with aninternal shoulder 26a-dapted tocontactwithshoul- -der .24 of the jet and secure same in'place, and

also provide for the quick removal of said jet for cleaning or replacement purposes.

The valve stem Hl consists of a combined needle valve point 21, having a plurality of fuel passages 2,8, which occupies the reduced portion I6 of the bore in the body of the valve with which the lateral fuel inlet opening l4 communicates, By reference to Fig. 5 it will be seen that the needle, portion of the stem in may be of triangular form'asshown, having said fuel passages 28 adapted to provide a direct passage for fuel from opening l4 out through the needle valve in any adjustment of the stem, either in a rotated or a longitudinal movement.

The valve stem is provided with a threaded portion 29 adapted to operate in the threaded portion ll of the body 9. The valve stem is further provided with a smooth cylindrical portion 30 adapted to extend into and operate at its end in the smooth bore portion l8 of the body and extend through the packing 3| and packing land H which is threaded at 32 in the body 9. Said stern extending out through the end of the gland and having mounted thereon the knob 33 secured by split pin 34 to enable the removal of the knob, the stem from the body and the gland from the stem.

To facilitate the disassembling of parts of the valve, flattened portions 35 are provided on opposite sides ofthe body portion 9 to-which may be applied a monkey Wrench or the like when removing gland l l and nut I3 from the body portion.

Having fully described my invention, What I claim and desire to secure by Letters Patent is:
